Aiming at the low-carbon economic dispatch of the integrated energy system，this paper constructs a low-carbon economic operation framework of the comprehensive energy system with multiple micro integrated energy systems，and a two-level optimal dispatch strategy of the integrated energy system considering the green certificates-carbon trading mechanism is proposed. Firstly，the carbon emission intensity and carbon emissions of each node in the energy network is calculated，which utilize the carbon emission flow model. Secondly，by analyzing the operation mechanisms of carbon trading and green certificate trading markets，the carbon trading，green certificate trading model of the micro integrated energy system are established，and green certificate-carbon trading linkage mechanism is designed to reduce the carbon trading fulfillment costs of micro integrated energy system. Then，a two-layer optimal dispatch model of integrated energy system under green certificate-carbon trading mechanism is established. The upper layer is the economic dispatch model of power grid and gas network. The lower layer is the low-carbon economic dispatch model of multi micro integrated energy systems considering the demand response with the goal of minimizing the operating cost. Finally，the calculation example shows that the proposed model can effectively reduce carbon emissions，decrease renewable energy waste，and achieve low-carbon economic operation of the integrated energy system. © 2024 Science Press.

Abstract ：
已有限流器优化配置方法大多以电阻、电感型限流器为配置对象,且只考虑每条线路均配置限流器的工况,降低系统经济效益,因此提出一种计及新型柔性直流限流器(novel flexible fault current limiter,NFFCL)运行特性、位置、数量等因素的优化配置方法.首先基于换流站和NFFCL简化模型,构建含NFFCL直流系统故障电流计算模型,并在 5 节点直流系统验证其准确性;其次,以NFFCL成本、限流效果为目标函数,以断路器最大开断电流为约束条件,构建多目标优化配置模型,并对NSGA-Ⅱ算法中的拥挤度计算进行改进,以实现优化配置过程中 NFFCL 安装数量与容量的解耦;最后,采用改进拥挤度计算的 NSGA-Ⅱ算法求解得到 11 节点直流系统的NFFCL优化配置方案,并通过限流器成本、安装数量、限流效果之间的关系选取最终方案.

Abstract ：
In order to realize the low-carbon emission of power system and boost the economic growth, a bi-level optimal dispatching strategy based on the demand response considering nodal carbon intensity is proposed, which uses the model of carbon intensity guided multivariate flexible load as basic. First, by using the principle of proportional sharing to track the carbon emission flow, a carbon emission flow model is built, and the carbon intensity variation law of each node is perceived from a spatiotemporal dimension. Then, the carbon flow analysis is incorporated into the load-side demand response mechanism, the nodal carbon intensity is used to establish the carbon emission model of demand response for load aggregators, and the dispatching differences of load aggregators under different carbon intensities are clarified to build a bi-level optimal dispatching model of power system based on demand response considering nodal carbon intensity. The upper-level of the model is the optimal economic dispatching of power grid operators, and the lower-level of the model is the demand response economic dispatching of load aggregators. Finally, the effectiveness of the proposed method is verified by a modified IEEE 30-bus system. © 2024 Automation of Electric Power Systems Press. All rights reserved.

Abstract ：
There is a problem that the inertia of DC microgrid is low and it is easy for the voltage of a DC bus to be affected by power fluctuation in the network. Thus an adaptive virtual inertia control strategy based on improved model prediction for grid-connected converter of DC microgrid is proposed. First, adaptive analog virtual synchronous generator control is introduced into the voltage outer loop and, by combining the inertial parameters with the voltage change rate, flexible adjustment of the inertial parameters is realized. Secondly, model predictive control is applied in the current inner loop, along with an improved delay compensation algorithm, to achieve fast tracking of the desired current value and enhance the dynamic characteristics of the control system. Finally, a system model is established based on Matlab/Simulink for simulation. The results show that, compared with the traditional virtual inertia control strategy, the DC bus voltage fluctuation amplitude of the proposed control strategy is smaller and the dynamic performance is better. This can effectively improve the stability of the DC bus voltage and the inertia of the DC microgrid. © 2024 Power System Protection and Control Press. All rights reserved.

Abstract ：
To address issues related to rapid increases in fault currents, high peak values, and the challenge of ensuring reliable power supply in non-fault areas within DC distribution networks, a novel fault current limiter for DC grids is proposed. The limiter design incorporates a bridge circuit to diminish peak fault currents, a coupling reactance for expediting fault transfer, and a primary current-limiting branch that employs pulse-width modulation to suppress fault currents. A coordinated strategy is introduced between the proposed limiter and DC circuit breakers, utilizing voltage differential criteria and directional overcurrent protection. The effectiveness and accuracy of the proposed solution are validated through simulation systems, and preliminary experiments are conducted. Results demonstrate that the proposed limiter effectively curtails fault currents, reducing fault current interruption by at least 90% compared to existing fault isolation methods. This successful implementation of the coordinated strategy ensures the avoidance of converter station lockouts and guarantees the system’s power supply reliability. © 2024 Power System Technology Press.

Abstract ：
In order to solve the problems of weak bidding ability and difficult market accommodation in high proportion wind power market，a bi-level Stackelberg game model of high proportion wind power coupled hydrogen energy storage system participating in spot market bidding is proposed. Firstly，the internal energy conversion relationship of the wind-hydrogen coupling system is studied，and the energy'time-space translation'mechanism of the wind-hydrogen coupling system is revealed. Considering the benefits of the wind-hydrogen coupling system and the cost of wind curtailment，the wind power bidding and hydrogen energy storage charging and discharging decision models are established. Secondly，taking into account the interests of wind- hydrogen coupling system and independent system operators，a market clearing model with thermal power units and wind-hydrogen coupling system as the main body is established based on Stackelberg game. Finally，aiming at the difficulty of solving the two-layer model，the KKT（Karush-Kuhu-Tucker）condition and strong duality theory are used to transform the bi-level model into a single-level mixed integer programming model which is easy to be solved. The simulation results show that the proposed strategy has played a positive role in the market consumption of high proportion of wind power. © 2024 Science Press. All rights reserved.
